3. Bootstrap a project

After installing plugins, scaffold your project with domain-specific docs, CLAUDE.md files, and templates:

/coordinator:bootstrap-project my-project

This delegates to each installed agent's bootstrap skill, creating a docs/ structure with per-domain documentation and conventions. Idempotent — safe to re-run after adding new plugins.

Thinking skills — the core of the marketplace

The thinking plugin is the most important piece. It provides structured reasoning skills, a learning system that improves over time, and project bootstrapping. Install it first.

/plugin install thinking@hpsgd

Reasoning skills

Invoke with /thinking:skill-name or let Claude auto-invoke when the context matches.
